Note on Some Properties of a Sandstone Block, After Use in a Glass Furnace

JSGT 1925 V09 T003-T011

 Mr J. Currie has described the columnar structure developed in sandstone blocks from Penshaw quarries after use in the lowest course of the sides of a tank furnace. The same phenomenon has since been noticed by other workers, some of whom have reported that this sandstone is very resistant to corrosion by the molten metal. It was thought, therefore, that a laboratory examination of Penshaw stone might be of some interest and might suggest an explanation of its successful use in furnace construction.
